They’re claiming DLSS4 (only available on their new cards) fixes a lot of these issues. But we’ll have to wait for the cards to get in the hands of reviewers before we’ll know for sure. I'm still pretty skeptical.

That said, if you read between the lines, it looks like the new 5090 is about ~40% faster than the 4090 at rasterisation. That’s a solid inter generational improvement.
